METALLIC WHEEL.

SPECIFICATION forming part of Letters PatentNo. 743,536, dated November 10, 1903.

Application filed August l. 1903.

To all whom it may concern:

, Be it known that I, WILHELM MEINRIOH, a subject of the Emperor of Germany, and a resident of Essen-on-the Ruhr, Germany, have invented certain new and useful Improvernents in Metallic Wheels, of which the following is a specification.

This invention relates to Wheels pressed from sheet metal; and the object of the invention is by combining two suitably-formed wheel-halves to produce a wheel with hollow spokes and a hollow telly which shall be of comparatively little weight and at the same time exceedingly strong and which shall resemble substantially in appearance the usual wooden wheels.

In the accompanying drawings is shown, by way of example, a construction of wheel according to this invention, the particular construction illustrated being adapted for heavy loads.

Figure 1 is a partial side elevation of the wheel. Fig. ,2 is a section on the line 2 2 of Fig. 1. Figs. 3 and 4 are sections of a spoke on the lines 3 3 and 4 40f Fig. 2, and Fig. 5 is a section of the folly on the line 5 5 of Fig. 1.

Each of the two halves A and B of the wheel is pressed from a metal sheet provided with sector-shaped spaces and has, as shown in the drawings, a hub portion, tapering spokes of semicircular section in a piece therewith, and a trough shaped felly. To join and stiffen the aforesaid parts, both halvesof the wheel are provided with flanges on their inner periphery at the spaces between the spokes and also with flanges on the outer periphery of the folly. The central aperture of the nave is surrounded bya flange to prevent tearing of the plates and to enable the wheel to be properly centered. Between both halves A and B of the wheel is inserted a spoke-plate 0, covered by the parts A and B, and which increases the strength of the wheel, the three parts A B 0 being united by rivets, screws, soldering, or welding. The hub portions of the plates A B G are also supported against each other by distance-rings D E F G, so as to admit of connection'with the hub being made sufficiently rigid.

The hub itself consists of the lined hubsocket H and two hub-plates K and L. These Serial No. 163,205. on, model.)

latter receive the wheel-plates between them and are drawn tightly together by screw-bolts M, passed through coincident holes in the hub-plates K L and through the hub portions of the wheel-plates A B C. To prevent the hub-plates from revolving on the hub-socket,

'C may be omitted, which will lighten the wheel.

Havingthus described the invention, the following is what is claimed as new therein:

1. A spoked wheel composed of two halves, each pressed from a single piece of sheet metal to form one-half of the hub, one-half of the spokes, one-half of the telly, flanges by which the two halves are secnredtogether, and which extend from the spokes throughout their length on both sides, and from the V inner and the outer peripheries of the folly, and a tire surrounding the folly and grooved for the reception of the flange on the outer periphery.

2. A spoked wheel composed of two halves, each pressed from a single piece of sheet metal to form one-half of the hub, one-half of the spokes, one-half of the felly, and flanges by which the two halves are secured together, and which extend from the spokes throughout their length on both sides, and from the inner and the outer peripheries of the folly; and a central plate having the form of the hub, the spokes and the follies and located between the two halves.

3. A s poked wheel composed of two halves, each pressed from a single piece. of sheet metal to form one-half of the hub, one-half of the spokes, one-half of the telly, and flanges by which the two halves are secured together, and which extend from the spokes throughout their length on both sides, and from the inner and the outer peripheries of the folly; and distance-rings positioned in the hub between the two halves.

tween the two halves; distance-rings positioned upon both sides of the central plate;

and a hub-plate on each side of the hub.

The foregoing specification signed at Dusseldorf this 22d day of July, 1903.

WILHELM MEINRICH.

In presence of WILHELM ESSENWEIN, PETER LIEBER.
